Hematite: A primary ore of iron and a pigment mineral Hematite Properties, uses, and occurrence of the most important ore of iron.

Oolitic Hematite: A specimen of oolitic hematite iron ore. Oolites are tiny round spheres of chemically precipitated hematite. The specimen in the photo is about four inches (ten centimeters) across, and the largest oolites are a few millimeters in diameter. What is Hematite? Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe2O3. It is a common rock-forming mineral found in sedimentary , metamorphic , and igneous rocks at locations throughout the world. Hematite is the most important ore of iron . Although it was once mined at thousands of locations around the world, today almost all of the production comes from a few dozen large deposits where significant equipment investments allow companies to efficiently mine and process the ore. Most ore is now produced in China, Australia, Brazil, India, Russia, Ukraine, South Africa, Canada, Venezuela, and the United States. Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore.

The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products. Hematite's Streak: All specimens of hematite will produce a reddish streak. The streak of a mineral is its color in powdered form when scraped across a streak plate (a small piece of unglazed porcelain used to produce a small amount of mineral powder). Some specimens of hematite will produce a brilliant red streak, others will produce a reddish brown streak. Care is needed when testing a specimen of hematite with a metallic luster. These specimens are often brittle and leave a trail of debris along with the streak. That debris is not a powder - it is a trail of fragments. So, to assess the streak, the loose particles must be gently shaken free from the streak plate or very lightly brushed off. This leaves behind the powder that is embedded within the textured surface of the streak plate. In the photo above, the streak on the left has been cleaned of fragments, and you can see that it is a reddish brown. The streak on the right still has a trail of glittery fragments that must be gently removed for proper evaluation.

Physical Properties of Hematite Trigonal Uses The most important ore of iron. Pigment, heavy media separation, radiation shielding, ballast, polishing compounds, a minor gemstone Physical Properties of Hematite Hematite has an extremely variable appearance. Its luster can range from earthy to submetallic to metallic. Its color ranges include red to brown and black to gray to silver. It occurs in many forms that include micaceous, massive, crystalline, botryoidal, fibrous, oolitic, and others. Even though hematite has a highly variable appearance, it always produces a reddish streak. Students in introductory geology courses are usually surprised to see a silver-colored mineral produce a reddish streak. They quickly learn that the reddish streak is the most important clue for identifying hematite. Hematite is not magnetic and should not respond to a common magnet. However, many specimens of hematite contain enough magnetite that they are attracted to a common magnet. This can lead to an incorrect assumption that the specimen is magnetite or the weakly magnetic pyrrhotite . The investigator must check other properties to make a proper identification.

If the investigator checks the streak, a reddish streak will rule out identification as magnetite or pyrrhotite. Instead, if the specimen is magnetic and has a reddish streak, it is most likely a combination of hematite and magnetite. Specular Hematite: Specular hematite, sometimes called "micaceous hematite," has a metallic luster and appears to be a rock composed of shiny mica flakes. Instead those flakes are hematite. Even though this hematite has a silver color, it still produces a reddish streak - which is a key to hematite's identification. Hardness testing on specular hematite is difficult because the specimens tend to crumble. This specimen is about four inches across (ten centimeters) and was collected near Republic, Michigan. Banded Iron Formation: Close-up of a banded iron formation. In this specimen, bands of hematite (silver) alternate with bands of jasper (red). The rock produced where these formations are mined is often called "taconite." This photo spans an area of rock about one foot (30 centimeters) wide. Photo taken by André Karwath, GNU Free Documentation License .

Composition of Hematite Pure hematite has a composition of about 70% iron and 30% oxygen by weight. Like most natural materials, it is rarely found with that pure composition. This is particularly true of the sedimentary deposits where hematite forms by inorganic or biological precipitation in a body of water. Minor clastic sedimentation can add clay minerals to the iron oxide. Episodic sedimentation can cause the deposit to have alternating bands of iron oxide and shale . Silica in the form of jasper, chert , or chalcedony can be added by chemical, clastic, or biological processes in small amounts or in significant episodes. These layered deposits of hematite and shale or hematite and silica have become known as the " banded iron formations " (see image). Massive Hematite: A specimen of massive hematite about four inches across (ten centimeters) collected near Antwerp, New York. Kidney Ore Hematite: Some hematite precipitates in cavities and has the opportunity to form an unrestricted habit. A habit known as "kidney ore" often develops in cavities and is named for its similar visual appearance to an internal organ.

This type of chemically precipitated hematite is often relatively uncontaminated with sedimentary clay or host rock inclusions and has a higher purity. The high purity makes this the hematite of choice for making pigments. This specimen is about four inches across (ten centimeters) and was collected near Cumberland, England. Geologic Occurrence Hematite is found as a primary mineral and as an alteration product in igneous, metamorphic, and sedimentary rocks. It can crystallize during the differentiation of a magma or precipitate from hydrothermal fluids moving through a rock mass. It can also form during contact metamorphism when hot magmas react with adjacent rocks. The most important hematite deposits formed in sedimentary environments. About 2.4 billion years ago, Earth’s oceans were rich in dissolved iron, but very little free oxygen was present in the water. Then a group of cyanobacteria became capable of photosynthesis. The bacteria used sunlight as an energy source to convert carbon dioxide and water into carbohydrates, oxygen, and water. This reaction released the first free oxygen into the ocean environment.

The new oxygen immediately combined with the iron to form hematite, which sank to the bottom of the seafloor and became the rock units that we know today as the banded iron formations. Soon, photosynthesis was occurring in many parts of Earth’s oceans, and extensive hematite deposits were accumulating on the seafloor. This deposition continued for hundreds of millions of years - from about 2.4 to 1.8 million years ago. This allowed the formation of iron deposits hundreds to several thousand feet thick that are laterally persistent over hundreds to thousands of square miles. They comprise some of the largest rock formations in Earth’s rock record. Many of the sedimentary iron deposits contain both hematite and magnetite as well as other iron minerals. These are often in intimate association, and the ore is mined, crushed, and processed to recover both minerals. Historically, much of the hematite was not recovered and was sent to tailings piles. More efficient processing today allows more hematite to be recovered from the ore. The tailings can also be reprocessed to recover additional iron and reduce tailings volume.

Martian "Blueberries": In 2004, NASA's Mars Exploration Rover Opportunity discovered that soil near its landing site contained millions of tiny spheres that researchers nicknamed "blueberries." Upon analysis, they were determined to be composed of iron oxide, mostly in the form of hematite. The iron content of Martian rocks and soil contribute to its red appearance from Earth and helped it earn the name "The Red Planet." Image by NASA. Hematite on Mars? NASA has discovered that hematite is one of the most abundant minerals in the rocks and soils on the surface of Mars. An abundance of hematite in Martian rocks and surface materials gives the landscape a reddish brown color and is why the planet appears red in the night sky. It is the origin of Mars' "Red Planet" nickname. Taconite Pellets: These taconite pellets consist of finely crushed taconite rock that has been processed to improve the iron content and mixed with a small amount of clay to improve pelletization. This is one of the standard ways of shipping iron ore from a mine to a steel mill.

The round particles are about 1/2 inch in diameter (1 1/4 centimeter) and are very easy to handle during shipping and at the mill. Image by Harvey Henkelmann. GNU Free Documentation License . Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world. These mines require investments of billions of dollars, and some will remove over 100 million tons of ore per year. These open-pit mines can be hundreds to thousands of feet deep and several miles across by the time they have been worked to completion. China, Australia, Brazil, India, Russia, Ukraine, South Africa, and the United States are the world’s leading producers of iron ore (includes hematite, magnetite, and other ores). Iron ore production in the United States occurs in Michigan and Minnesota. Hematite Pigment: Hematite was one of the first pigment minerals used by people.

At least 40,000 years ago, people obtained hematite, crushed it into a fine powder, and used it to make paints. Shown above are commercial hematite pigments that are available today. From top left, going clockwise, they are: Blue Ridge Hematite, Blue Ridge Violet Hematite, Venetian Red, and Pozzuoli Red. Since the Renaissance, pigments have often been named after the locations where they were produced. The color variations are a result of the type of hematite used and the impurities, such as clay and other iron oxides, that are commingled with it. Hematite gems: Hematite and taconite are often made into tumbled stones or cut into cabochons and beads. These are popular as inexpensive jewelry items. Tumble-polished hematite is also popular as a "healing stone." Some people believe that carrying it will help relieve certain medical problems. This use has no scientific merit and can actually be harmful because it diverts people who need medical attention from seeing a doctor.

Uses of Hematite (Pigment) The name hematite is from the Greek word "haimatitis" which means "blood-red." That name stems from the color of hematite when it has been crushed to a fine powder. Primitive people discovered that hematite could be crushed and mixed with a liquid for use as a paint or cosmetic. Cave paintings, known as " pictographs ," dating back to 40,000 years ago were created with hematite pigments. Hematite continues to be one of the most important pigment minerals. It has been mined at many locations around the world and has been traded extensively as a red pigment. During the Renaissance when many painters began using oils and canvas, hematite was one of the most important pigments. Hematite color was opaque and permanent. It could be mixed with a white pigment to produce a variety of pink colors that were used to paint flesh. The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties. Inexpensive mineral collections are available in the Geology.com Store .

Uses of Hematite (Gem Material) Hematite is a minor gem material used to produce cabochons, beads, small sculptures, tumbled stones , and other items. The material used to manufacture these products is a silver-colored hematite with a solid, uniform texture. The bright silver color of hematite and its "weighty feel" make it a very popular tumbled stone. Hematite Novelties: Products called "magnetic hematite" and "iridescent hematite" are often offered for sale in gift, tourist, novelty, and science shops and their websites. Most of the time these materials are not hematite but are man-made materials that do not even have the same chemical composition as hematite. Buy them if you like them but not because you think that you are getting a unique mineral specimen. Uses of Hematite (Healing Stone) Some people believe that carrying pieces of tumble-polished hematite, known as "healing stones," will bring relief from certain medical problems. There is no scientific proof that this use of hematite has any positive effect beyond being a placebo.

Using hematite as a "healing stone" or a "healing crystal" can actually be harmful because it diverts people from seeing a doctor who can provide proper care. Then when the person with the problem finally decides to see a doctor, their situation is more severe. Iron Furnace: In the 1700s and 1800s, small mines in the eastern United States produced hematite which served as the primary iron ore of the region. The ore was processed by heating it by burning charcoal in simple stone furnaces. The iron ore deposits were small and difficult to exploit. When the large iron ore deposits of the Great Lakes region were discovered, iron ore was no longer mined in the eastern United States. Shown is the Vesuvius Iron Furnace of southern Ohio. USGS photo. Other Uses of Hematite Hematite is used for a number of other purposes. It is a very dense and inexpensive material that is effective at stopping x-rays. For that reason it is used for radiation shielding around medical and scientific equipment. The low cost and high density of hematite and other iron ores also makes them useful as ballast for ships.

Hematite can also be ground to a fine powder that when mixed with water will make a liquid with a very high specific gravity. These liquids are used in the "float-sink" processing of coal and other mineral material. The crushed coal, which has a very low specific gravity, is placed on the heavy liquid and the light clean coal floats, while high-specific-gravity impurities such as pyrite sink. Finally, hematite is the material used to make polishing compounds known as "red rouge" and "jeweler's rouge." Red rouge is a hematite powder used to polish brass and other soft metals. It can be added to crushed corn cob media or crushed walnut shell media for tumble-polishing brass shell casings. Jeweler's rouge is a paste used on a soft cloth to polish gold and silver jewelry.

Size: 28 Views: 15 What is a metal ore? a rock containing a metal, or a metal compound, in high enough concentration to make it economic to extract the metal. Metals are produced when metal oxides are reduced (have their oxygen removed). [info] The reduction method depends on the reactivity of the metal. For example, aluminium and other reactive metals are extracted by electrolysis, while iron and other less reactive metals may be extracted by reaction with carbon or carbon monoxide. Advertisement ) a reaction with carbon or carbon monoxide copper how are they extracted?

using various ways The method of extraction of a metal from its ore depends on the metal's position in the reactivity series. Gold, because it is so unreactive, is found as the native metal and not as a compound The transition metals are placed in the periodic table in a large block between groups 2 and 3. Most metals (including iron, titanium and copper) are transition metals. they are good conductors they can be bent into shape easily [transition metals are shown in yellow on flip side] Is copper a good or bad conductor? GOOD Copper is soft and easily bent and so is a good conductor of electricity, which makes it useful for wiring. Copper is also a good conductor of heat and it does not react with water. This makes it useful for plumbing, and making pipes and tanks. How can copper be extracted? Copper can be extracted from ores by heating them in a furnace, a process called smelting. The copper is then purified using a process called electrolysis. How is Iron extracted? Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind.

Reactions in which oxygen is removed are called reduction reactions. Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. What is this method of extraction called? This method of extraction is called phytomining. Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds.What is this method of extraction called? This method of extraction is called bleaching. Aluminium and titanium are two metals with a low density. Which one of the following are they: 1) heavy 3) liquids 2) light Aluminium and titanium have a very thin layer of their oxides on the surface. What does this mean they are useful for? Thi oxide layer stops air and water getting to the metal, so aluminium and titanium resist corrosion. Aluminium is used for aircraft, trains, overhead power cables, saucepans and cooking foil. Titanium is used for fighter aircraft, artificial hip joints and pipes in nuclear power stations. Unlike iron, aluminium and titanium cannot be extracted from their oxides by reduction with carbon.

You do not need to know any details of how these metals are extracted, but existing methods are expensive because: the processes have many stages large amounts of energy are needed Aluminium is extensively recycled because less energy is needed to produce recycled aluminium than to extract aluminium from its ore. Recycling preserves limited resources and requires less energy, so it causes less damage to the environment. The properties of a metal are changed by adding other elements to it. A mixture of two or more elements, where at least one element is a metal, is called an alloy. Alloys contain atoms of different sizes, which distort the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal. Advertisement Pure copper, gold, iron and aluminium are too soft for many uses. They are mixed with other similar metals to make them harder for everyday use brass, used in electrical fittings, is 70 percent copper and 30 percent zinc 18 carat gold, used in jewellery, is 75 percent gold and 25 percent copper and other metals duralumin, used in aircraft manufacture, is 96 percent aluminium and 4 percent copper and other metals.

Pure Iron is too soft for many uses.Iron from the blast furnace is an alloy of about 96 percent iron with carbon and some other impurities. It is hard, but too brittle for most uses, so most iron from the blast furnace is converted into steel by removing some of the carbon. How would you remove the carbon? Carbon is removed from molten iron by blowing oxygen into it. The oxygen reacts with the carbon, producing carbon monoxide and carbon dioxide, which escape from the molten metal. Enough oxygen is used to achieve steel with the desired carbon content. Why can gold be found in the Earth's crust in its native state? because Gold is very unreactive. Why is aluminium extracted from aluminium ore by electrolysis? because Aluminium is more reactive than carbon. Why is iron extracted from iron ore by reduction with carbon or carbon monoxide? because Iron is less reactive than carbon. What happens to iron oxide in a blast furnace? Iron oxide is reduced to form iron. in comparison with steel, what is pure iron like? pure iron is softer than steel What is the percentage of iron in the iron from a blast furnace?

the percentage of iron from a blast furnace is 96% Which type of steel is likely to be used for making cutlery? cutlery is made from Stainless steel What process is used to purify copper? Electrolysis is used to purify copper Why is titanium expensive to extract from its ore? Titanium is expensive to extract from its ore because Several stages are involved. What does Phytomining involve? Phytomining uses plants to absorb metal compounds Copper can be obtained by reacting solutions of copper compounds with scrap iron.

Justin , LSU BBC - GCSE Bitesize: Making iron In the blast furnace Blast furnace in a modern steel works Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. Carbon is more reactive than iron, so it can push out or displace the iron from iron oxide. Here are the equations for the reaction: iron oxide + carbon → iron + carbon dioxide 2Fe2O3 + 3C → 4Fe + 3CO2 In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.

In the blast furnace, it is so hot that carbon monoxide can be used to reduce the iron oxide in place of carbon: iron oxide + carbon monoxide → iron + carbon dioxide Fe2O3 + 3CO → 2Fe + 3CO2 Raw materials for the reaction The raw materials for extracting iron and their function in the process Raw material magnetite, hematite, limonite and siderite are ores of which metal magnetite, hematite, limonite and siderite are ores of which metal magnetite, hematite, limonite and siderite are ores of which metal Milling is also known as grinding, it is a material more refining process.

Extraction of Iron from Haematite | Lets Learn Nepal Extraction of Iron from Haematite Valency: 2 and 3 Electronic Configuration: 1s2, 2s2, 2s6, 3s2, 3p6 , 3d6, 4s2 Occurrence: Iron is the fourth must abundant metal in this universe. Due to its high reactivity, it rarely occurs in free state.

The main ores of iron are: Oxide Ores: Haematite (Fe2O3), Magnetite Fe33O4 Carbonate ores: FeCO3 (Clay iron stone) Note: Iron is mined and smelted extensively in different parts of Nepal since 200 years before, but at present but none of the mine is in operation at present. Extraction of Iron: Iron is extracted from its chief ore Haematite Fe2O3. The various steps involved in the process are as follows: 1. Crushing: The ores are crushed in jaw crusher and powdered in ball mills. 2. Concentration: The crushed ore is washed with steam or cold water to remove clay and sand. The washed ore is then concentrated by electromagnetic separation process. 3. Calcination: The concentrated ore is then heated strongly in presence of air. This process is called calcination. During calcination: Moisture is driven out. Ferric oxide changes into ferric oxide. $$\ce{4FeO + O2->2Fe2O3}$$ 4. Smelting: The calcinated ore is now reduced in the metallic iron chamber called blast furnace. This process is called smelting.

Blast furnace is a cylindrical tall tower like structure made up of iron sheet. The systematic diagram of blast furnace and different zones are described below. Blast Furnace Combustion Zone (Lower Zone): In this zone, carbon burns in presence of hot air. The reaction is exothermic and hence temprature rises to 1500o C. $$\ce{C + O2->[\Delta]CO2}$$ Here, Carbon Dioxide rises upwards and mixed with red hot coke. It is reduced to carbon monoxide. The reaction is endothermic and the temperature drops to 1200oC. $$\ce{CO2 + C->2CO}$$ Reduction zone: At the temperature of 500-7000oC, the oxide ore is reduced to spongy ion in this zone. $$\ce{FeO + CO->Fe + CO2}$$ Slag formation zone: As the temperature ranges 800-1000oC, the limestone present in the charge decomposes into calcium oxide and carbon dioxide. $$\ce{CaCO3 ->CaO + CO2}$$ This lime acts as a flux as it combines with silica.

$$\ce{CaO + SiO2->CaSiO3}$$ Note: Silicates, phosphates and Manganates are reduced to Si, P and Mn here. Zone of Fusion: The molten slag being lighter floats on the top. The slag and molten metals are removed from the respective holes. The molten iron tapped off from the furnace is solidified into blocks known as pig. This forms an iron called pig iron or cast iron which is called pig iron or cast iron. The iron thus obtained contains 93% iron, 5% carbon and 2% of other impurities. This iron is further purified as per needed. Do you like this article ?
